DISK HARROW.

Specification of Letters Patent.

Patented July 23,1912.

Application filed. July 13, 1910. Serial No. 571,832.

To all whom/"it may concern:

Be itknown that I, AUGUsT IANDGREN. of Molina, county of Rock Island. and State of Illinois, have invented a new and useful Improvement in Disk I-Iarrows, of which the following is a specification.

This invention relates to disk harrows and cultivators of the type en'ibodying a sustaining frame equipped with gangs of disks, the object of the invention being to produce a machine of this character particularly suitable for operation in orchards. vineyards and like localities, where the foliage closely overhangs the ground.

With this end in View. my invention consists of various improved features of con; struclion in the general organisation of the machine designed to reduce the height of the same to a minimum. and directed to the manner of mounting and sustaining the disk to permit their easy. quick and universal adjustments to the form and con struction of the sidp is a top plan view of my improved manhine. u 2 if :1 blllll LlUxiillUll mi ilk sumo. pl".

.cti n liw iiizj it: a iine aa of Fig. Fig. i is a long sectional elevation on the line Zi 7; of Fig. 1 through the dish gang, the fr:nn-.= of the innchinfl and the devices by which he gangs are supported from the frame. Fig. 5 is a 'iiew, showing in prrspmtstim. ih detailed parts of the devices by which tin; disk rungs are supported from the frame. F1". (5 is a lilil,"

the like of travel; and reversed end to end perspective View of an auxiliary ush :idapt ed to be dctachahly' applied to the end oi 1 the disk gai fective length of the gang.

in order to increase the ei' Fig. 7 is an,

elevation showing titeform of the end dish 2 of the gang to adapt the same to have the auxiliary disk applied to it. Fig. 8 is a top plan View of my improved machine showing" the same provided with the extension frames by which the dish gangs are spread or supported at. agreater distance apart than is possible by the main frame.

Referring to the drawings: 1 represents a supporting frame, consisting in the present instance of a rear frame bar 2 and two forward frame bar members 3. which extend forwardly front the ends of the rear memher and have their forward ends firmly fixed to the sides of a draft tongue 4. fixed at its rear end by suitable means to the rear frame bar 2. At. its rear end. the tongue gives support to a seat bracket 5. to which a drivers seat 6 is connected, the arrangement of these parts being such that the driv crs seat will be sustained close down to the level of the frame. At its forward end the frame, as shown in Fig. 2, is supported by a truck 7 and the draft may be applied to the tongue in any suitable manner, either by the doubletree construction 8 shown in Fig. l, or by the menu draft attachment shown in Fig. t or by other suitable means.

The "ante ('arries. in rear of the rear frame bar 2. disk gangs 9, there being two in the present instance. one at each side of the frame. and ouch gang comprising a plural ity of disks ll. 10, etc. These disk gangs are connected with the frame bar 2 in such manner that they may be adjusted bodily along said frame bar to and from each other to vary the dimance between the gangs; adjusted bodily around a fore and aft horizontal unis to vary the inclination of the disks with ieferenixe in the surface of the ground; Fwd nr in'ni u \r', nrul axis to vary the .atitz-n of the dit is with reference 1''? in order to ndapt the disks to throw the soil either inwardly or outwardly, The devices for connwting the disk gangs to the frame to uiiupi them in be adjusted in the manner mentioned conshts in each case preferably of u bracket mmnber 11, in the form of a wide plate having its front end bent downwardly and applied to the rear side of the frame bar 2, to which it is adjustahly secured by the means presently to be tie-- scribed, whence the plate extends rearwardly and upwardly and is provided with a horixontal fiat portion ll. Depending from the center of this flat. portion. is a piv oting stud 12. passed. at its upper end through the pla e and extending at slower end through a brace strap 13, the forward end of which is firmly secured to the body portion of the plate by means of a bolt 14, or by other suitable means, this construction sustaining the pivoting stud firmly and rigidly in an upright position. Mounted loosely on the pivoting stud between the late and brace strap is a'collar 15, extend mg laterally at its upper end in opposite directions and formed with a socket 15*, and extending also at its upper end rearwardly, which rearwardly extending portion is provided with a socket 15*, the purpose of which will presently appear. Seated in the socket 15 and beneath the rearward extension 11 of the plate, is a disk gang carrying-yoke 16, through which the pivoting stud 12 extends, and which yoke extends downwardly at its ends and has fixed to said ends journal sleeves 17, in which a shaft 18 is mounted, and on which shaft the disks of the gang are in turn mounted.

By the construction described, it will be observed that the disk gang is carried on the underside of the bracket member or plate in such manner that the gang may turn around a vertical axis represented by the pivoting stud 12. whereby the inclination of the disks to the line of draft may be varied. The entire gang may be turned end for end so that the disks will face either outwardly, as shown in the drawings, or may face inwardly, this being effected by withdrawing the pivoting stud 12, removing the yoke 16 from its socket, reversing the yoke end for end and again applying the pivoting stud before, to hold the yoke in its reversed posi tion.

In order that i113 bracket members carry ing the disk gangs may be adju ted bodily to and from each other along the frame bar 2, and in order that the gangs may also be ad'usted around a fore and aft longitudinal 4 axis, the forward downwardly cxtcndihg 1 portion of the plate is provided in opposite ends with curved slots 11, through which horizontal bolts 11 extend. and at the upl per and lower edges of the frame bar 2. 4 which bolts pass through vertical straps 11* appliedto the front side of the frame bar, 1

-bv which means the bracket members may frame menilx-rs are adapted to be fixed debe clamped firmly and fixedly to the frame bar. This construction admits of the bracket member being set in different sitions along the frame bar, and also admits of the said member being adjusted around a longitudinal fore and aft axis, which latter adjustment is effected by tippin the bracket member relative to the frame liar, which tipping action is permitted by the curved slots 11.

In order that the driver may conveniently effect the adjustments of the gangs around the vertical pivoting tud in order to vary the inclination of the disks to the line of travel. I provide adju ting levers lJ pivoted at their lower ends, as at 20, to the lower ends of segment frames 21 fixed to the opposite sides of the tongue, respectively, the said segment frames being provided with locking teeth adapted to be engaged by locking dogs on the levers, in order that the latter may be held in the ditferent positions set. Connected to the levers, respectively, are two rearwardly extending longitudinal links 22, which are jointed at their rear ends respectively to the inner ends of adjusting arms '23, whose outer ends extend in the sockets 15 of the sleeve 15, respectively, in which they are adapted to be firmly fastened in different positions by means of fastening bolts 24, or by other means. As a result of this construction, whenthe levers are thrown forwardly. they will act. through the connection with the adjusting arms, to shift the disk gangs on the pivoting studs 12 to the position shown in Fig. 1: and when thrown rcarwardly, they will act to shift the gangs in the opposite direction. By connecting the end of the adjusting arm '23 adjustably in the :Ut'litfl in the collar 15. the lateral ad jnstnient of the gangs is permitted without attracting the longitudinal positions of the conne ting links, it being but necessary, when the gangs are adjusted to and from each other. to correspondingly adjust the ends of the adjusting arms in the sockets, the said arms being provided with a number of holes 2 3 to receive the fastening bolts 24.

Bv constructing the bracket members in the form of wide plates. as described, they act in addition to their function of carrying the disks as shields for the disks. and re- \rnt the contact of the foliage with the disks, thereby avoiding injury to the foliage. These bracket members therefore constitute in ctl'cct. combined disk-carrying and guard plate serving the two-fold function-of affol-din; a means for sustaining the disks and also of guarding the overhanging foliage from injury thereby.

In order that the disk gangs may be spread or set at a greater distance apart than the length of the frame bar 2 of the main Ii-atti will peunit. I provide supplemental frame members '25. as Shown more particularly in Fig. 8. which supplemental frames to the rear and front frame members respectively of fastening bolts '2 the rear limbs of the of the main frame. by means Esupplcmental frame when thus applied forming outwardly extending ctmtinuations of the rear fl'tlllli' bar it uf the main frame.

The bracket members 11 are connected with the supplemental frame nembcrs in a man ner similar to that described in their ap plication to the main frame, and in order that when so connected the adjusting arms 23 may be'opcrated by the hand levers Without shifting or changing the positions of the longitlulinal links pi, i provide lateral connecting links 26, jointed at their inner ends to the longitudinal links; and connected at their outer ends adjustably with the inner ends of the adjusting arms by bolts 26 or otherwise. lly this construction, it will be seen that. it is possbile to set the disk gangs at a considerably greater distance apart than is possible when thegangs arelapplicd to the main frame, whicli adjustments are found to be necessary under certain conditions encountered in the use of the machine in the field.

In order that the eii'cctive length of the disk gangs may be increased, 1 provide for the attachment to the end disk of the gang of an auxiliary disk JP, shown in Fig. (3. This auxiliary disk has fixed. to its ct nter an axially extending hub portion 8, provided on its end with a .ateral flange 29, provided with perforated lugs $10. In the application of the disk to the end disk of the gang, the flange is seated llatly a inst the convex surface of the end disk and firmly secured thereto by means of bolts passing through the perforated lugs on the flange and holes 31 in the end disk lVhile in the accompanying drawings l have shown my invention embodied in the specific form which I prefer to adopt, and which in practice has been found to answer to a satisfactory degree the ends to be attained, it will be understood that the invention is not limited to any particular form or details except in so far as such limitations are specified in the claims.
